tidy3d.AbsorberParams#

class AbsorberParams[source]#

Bases: Tidy3dBaseModel

Specifies parameters common to Absorbers and PMLs.

Parameters:

sigma_order (NonNegativeInt = 3) – Order of the polynomial describing the absorber profile (\(\mathrm{dist}^{\text{sigma\_order}}\)).
sigma_min (NonNegativeFloat = 0.0) – [units = \(2\epsilon_0/\Delta t\)]. Minimum value of the absorber conductivity.
sigma_max (NonNegativeFloat = 1.5) – [units = \(2\epsilon_0/\Delta t\)]. Maximum value of the absorber conductivity.

Example

>>> params = AbsorberParams(sigma_order=3, sigma_min=0.0, sigma_max=1.5)
